Goal Story MCP Server

Instructions

Implementation Reference

• src/index.ts:538-562 (handler)

  The MCP tool handler implementation for 'goalstory_update_step'. It makes a PATCH request to the backend API at /steps/{id} with the provided updates (name, status, outcome, evidence) and returns the formatted response.

    UPDATE_STEP_TOOL.description,
    UPDATE_STEP_TOOL.inputSchema.shape,
    async (args) => {
      const url = `${GOALSTORY_API_BASE_URL}/steps/${args.id}`;
      const body = {
        id: args.id,
        ...(args.name ? { name: args.name } : {}),
        ...(typeof args.status === "number" ? { status: args.status } : {}),
        ...(args.outcome ? { outcome: args.outcome } : {}),
        ...(args.evidence ? { evidence: args.evidence } : {}),
      };
      const result = await doRequest(url, "PATCH", body);
      return {
        content: [
          {
            type: "text",
            text: `Step updated:\n${JSON.stringify(result, null, 2)}`,
          },
        ],
        isError: false,
      };
    },
  );
  
  /**

• src/tools.ts:273-298 (schema)

  The tool definition object containing name, description, and Zod inputSchema used for registration and validation.

  export const UPDATE_STEP_TOOL = {
    name: "goalstory_update_step",
    description:
      "Update step details including the name, completion status, evidence, and outcome. Use this to track progress and insights.",
    inputSchema: z.object({
      id: z.string().describe("Unique identifier of the step to update."),
      name: z
        .string()
        .optional()
        .describe("Refined or clarified step description."),
      status: z
        .number()
        .optional()
        .describe(
          "Step completion status: 0 = pending/in progress, 1 = completed.",
        ),
      outcome: z
        .string()
        .optional()
        .describe("Results and impact achieved through completing this step."),
      evidence: z
        .string()
        .optional()
        .describe("Concrete proof or observations of step completion."),
    }),
  };

• src/types.ts:80-87 (schema)

  TypeScript interface defining the input parameters for updating a goal story step.

  export interface GoalstoryUpdateStepInput {
    id: string;
    name?: string;
    status?: number; // 0=Pending, 1=Complete
    outcome?: string;
    evidence?: string;
    notes?: string;
  }

• src/index.ts:42-43 (registration)

  Import of the UPDATE_STEP_TOOL constant used to register the tool handler.

    UPDATE_STEP_TOOL,
  } from "./tools.js";

• src/index.ts:62-122 (helper)

  Shared helper function doRequest used by all tool handlers to make authenticated HTTP requests to the backend API.

  async function doRequest<T = any>(
    url: string,
    method: string,
    body?: unknown,
  ): Promise<T> {
    console.error("Making request to:", url);

          Authorization: `Bearer ${GOALSTORY_API_TOKEN}`,
        },
        data: body,
        timeout: 10000, // 10 second timeout
        validateStatus: function (status) {
          return status >= 200 && status < 500; // Accept all status codes less than 500
        },
      });
      console.error("Response received:", response.status);
      return response.data as T;
    } catch (err) {
      console.error("Request failed with error:", err);
  
      if (axios.isAxiosError(err)) {
        if (err.code === "ECONNABORTED") {
          throw new Error(

          );
        }
